Evo350Z Adjustable Upper A Frame
Just wondering if anyone has installed these to fix the tire feathering issue?
If so, would these help even if you don't want to lower your vehicle?
Thanks

I have the EVO's on my Z -- it's been more than a month now -- and they seem to have corrected the problem. I say seem because my Z's still riding on the feathered tires. What I can tell is that more of the tire is making contact with road, and the inner tread blocks aren't getting the "work-out" like they did before the A arms -- the tech set the front camber to -.3 degrees.
Feathering started on my Z after about 9K or so; what's interesting is this was about the point in time I replaced my plenum which requires you to remove the crossbar. Nissan has the crossbar adjusted to push the shock-towers apart which I think affects the camber in a positive direction.
Nissan's Service Manual permits a camber range of +.17 to -1.33 degrees. Over time as the rubber bushings deteriorate/sag the suspension develops more negative camber--this is what I'm told. My guess is, depending on where a given Z is, camber wise, when it rolls off the assembly line, the front suspension will likely sooner or later develop more negative camber to the point where the tires will wear abnormally.
Nissan's engineers clearly did not anticipate this problem and apparently think it's too costly for them to correct. In my view, if you plan on keeping the car, purchase a set of adjustable A-arms. Going back and forth to the dealer for tire-wear is not worth the headache.
